God has given us the day, we can use it as we like. We can waste it, or grow in its light and be of service to others. But what we do on the day is important, as we have exchanged a day of our life for it. When tomorrow come,today will be gone. I hope I will not regret for the price I paid for the day.
Life is beautiful, together let us make each of our life, and other people's life more beautiful...

Haiti Earthquake 2010 - why it happen?
Scientifically
The Caribbean island nation of Haiti has been beset by a series of natural disasters in recent years, experiencing four devastating tropical storms in 2008.
Tuesday's 7.0-magnitude earthquake will only further complicate living conditions for residents of the poverty-stricken country where 80 per cent of Haiti's nearly nine million people live below the poverty line.
The movement of Caribbean plate The quake occurred in the vicinity of the northern boundary where the Caribbean tectonic plate shifts eastwards by about 20 mm per year relative to the North American plate. The strike-slip fault system in the region has two branches in Haiti, the Septentrional fault in the north and the Enriquillo-Plaintain Garden fault in the south; both its location and focal mechanism suggest that the January 2010 quake was caused by rupture of the Enriquillo-Plaintain Garden fault, which had been locked solid for 250 years, gathering stress. The stress would ultimately have been relieved either by a large earthquake or a series of smaller ones. The rupture of this Mw 7.0 earthquake was roughly 65 kilometres (40 mi) long with mean slip of 1.8 metres (5.9 ft). Preliminary analysis of the slip distribution found amplitudes of up to about 4 metres (13 ft) using ground motion records from all over the world
